What is BOTOX® Cosmetic?
BOTOX® Cosmetic is the trade name of Botulinum Toxin Type A, a purified natural protein toxin produced by the bacterium Clostridium Botulinum, and is the registered trademark of Allergan Inc. In controlled small doses, it is injected directly into the muscles that cause frown lines. These isolated muscles are relaxed by BOTOX® Cosmetic and can no longer contract. Because the specific muscles no longer contract, the action of frowning is stopped and the frown lines soften, relax, and diminish.
Where Can BOTOX® Cosmetic Be Injected?
The most common areas of use of BOTOX® Cosmetic are the frown lines between the eyebrows, horizontal forehead lines, and crow’s feet. On occasion, some other areas may be treated as well.
When Does BOTOX® Cosmetic Start to Work and How Long Does It Last?
The results of your BOTOX® Cosmetic treatment will begin to appear in three to four days. The effect will last three to four months, after which the treated muscles will gradually regain their action. When the lines begin to reappear, a simple repeat treatment is all that is necessary to maintain the desired results.
How Safe Is BOTOX® Cosmetic?
BOTOX® Cosmetic has been used safely and successfully in ophthalmology for over 10 years and for wrinkle therapy for over 6 years. In the amounts used for wrinkle therapy, the only possible side effects are temporary and localized to the area of injection.
What Side Effects May Be Experienced?
As with any injection, there can be temporary swelling, redness, bruising, headache or local discomfort. Rarely, patients have been reported to develop a slight lowering of the eyelid or slight lowering of the forehead. This is temporary and resolves in a few weeks. Some patients may have an uneven or incomplete response to the treatment. BOTOX® Cosmetic does not reduce the action of the muscles of facial expression distant form the site of treatment. Patients with neuromuscular disorder should inform their doctor before therapy. BOTOX® Cosmetic treatment should not be administered to women who are pregnant.
